CASTER.

$PECIFIGATION forming part of Letters Patent No. 498,130, dated May 23, 1893.

Application filed July 15, 1892. Serial No.440, 176. (N0 model.)

To all whom it may concern.-

Be it known that I, CARL F. MANKEY, a citizen of the United States, residing atEmporium,in the county of Cameron, State of Pen nsylvania, have invented certain new and useful Improvements in Casters, of which the following is a specification, reference being had therein .to the accompanying drawings.

This invention relates to certain new and useful improvements in casters, and it has for its object to provide a cheap and simple caster socket, readily applied and by which the caster will be held against accidental displacement. I form a two-part socket with a longitudinal slit in one part through which works a spring tongue, which tongue is formed integral with the track-plate. The shank of the caster has a bulb or enlargement to engage the end of the spring tongue. The trackplate may be of cast or sheet metal as may be desired. The socket may be of one piece if desired.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a vertical section through a portion of a leg with my socket and caster in place. Fig. 2 is a perspective view of the socket and track-plate detached.

Like letters of reference indicate like parts in both of the views. I

Referring now to the details of the drawings by letter, A designates a portion of a leg, say of a bed, having a socket a for the reception of the socket B which may be of two pieces or of one piece of sheet metal. This socket is designed to be inserted in the socket of the leg in the usual manner.

as seen in Fig. 1.

C is the caster the shank c of which is provided with a bulb or enlargement c as seen in Fig. l to engage the spring tongue of the track-plateand prevent the caster from. falling out.

D is the track-plate formedpreferably of sheet metal and with a tongue at which is designed to extend through a longitudinal slot or slit 6 in the socket and bear against the bulb orenlargement on the shank of the caster The under side of the track-plate is concave as shown to receive the lower end of the socket.

The operation will be apparent. The caster can be Withdrawn when desired by a sudden pull thereon. The tongue should be of a length slightly less than the length of the slit or slot 6 so as to permit of its readyinsertion.

What I claim as new is 1. The combination with a socket having a longitudinal slot, of a track-plate formed with an integral spring tongue adapted to work through said slot, as set forth.

2. The combination with a socket having a longitudinal slot, of a track-plate having an integral spring tongue, and a caster havinga shank with an enlargement between its ends to engage said tongue, as and for the purpose specified.

3. The combination with a metallic socket having a longitudinal slot near its outer end, of a track plate independent of said socket and formed with integral spring tongue extending through said slot and bent in line with the slot, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CARL F. MANKEY.
